TU'aZZ whom it mar concern:

Be it known that ALBERT L. THOMPSON, citizen of the United States,residing at Fall River, in the county of Bristol and State ofMassachusetts, has invented certain new and useful. Improvements inSpinning Rings, of which the following is a specification, referencebeing had therein to the accompanying drawin This mvention has referenceto means for automatically and uniformly lubricating the ring andtraveller elements of spinning or spooling machinery such as used in thecot-v ton, woolen and silk textile industries.

According to prevailing practice, the spinning ring is lubricated byhand a plication of the oil to the inner surface of the ring but .thismethod of application has proven to be unreliable, costly and wasteful,for the reason that it is practically impossible to eifect equaldistribution of the oil toall parts of the moving machinery as requiredwith the result that certain parts of the machinery are subjected togreat wear causing wastage of both power and oil.

The purpose of my invention is to eliminate the foregoing objections bythe provision of a self-lubricating spinning ring shaped to provide anintegral oil reservoir extending entirely around the ring and providedwith a series of spaced outlets leading from the bottom of the reservoirto the inner surface of the ring.

A further purpose of the invention is to provide a ring of the characterspecified which is so designed as to ermit the same to be manufacturedand sol for a comparatively reasonable sum.

Other purposes, advantages and characteristic features of the inventionwill be more readily understood from the following detailed descriptionand drawings wherein I have disclosed what I now consider to be,

a preferred embodiment.

In the drawing:

Fi ure 1 is a plan view of a spinning r ng constructed in accordancewith my raven tion.

Figure 2 is the transverse sectional View of the ring.

. 8 for engagement with the usual type of signature.

' Referring more particularly to the draw-' ings, 5 discloses a spinningring formed with a smooth, vertical, inner surface 6; At the outersurface the ring is formed, between its upper and lower'edges, with anannular enlargement or rib 7, having its upper edge portionextendedoutwardly from the body of the ring to provide a supportingflange ring rail. Between the flange 8 and the body of the ring 5, theupper surface of the rib 7 is provided with an annular groove 9 havingside walls inclining inwardly toward the axis of the ring so that thegroove extends partly through the ring body. The bottom portion of thisgroove is in communication with the inner vertical surface of the ringthrough a plurality of relative openings 10, passing through the ringbody at right angles thereto. i y

In order to prevent the oil from escaping too freely from the groove orreservoir 9, I prefer to place in said reservoir an annular wick 11,which serves to hold the oil in suspension while permitting suflicientoil to be drawn through the openings 10 to uniformly r-Arenr orrlcs.

lubricate'the in'nersurface of the ring and body, an annular flangeprojecting outwardly from the body between its lower and upper edges,said body being rovided with an annular oove formed t erein at the baseof said ange, said groove being formed with inner and outer wallsinclining toward the axis of the ring as they approach the bottom of thegroove, and said body being formed with a plurality of small openingsextending inwardly from the said bottom of the groove to the innersurface of the body.

In testimony whereof I hereunto aflix my ALBERT L. THOMPSON.
